It will but if somehow you could tie into the 3/4" lines instead it would give you more flow. More flow= more pressure.

3/4 Pex, with 3/4 to 1/2 Sharkbite reducer would work.

most faucets with 3/4 feeds should stay 3/4 to provide volume so the faucet can operate as it is suppose to ..imo 1/2" supply would not work....its 3/4 for a reason...

Yes you could but why not cut in a 3/4" tee before the manifold and run just one line instead?

ndmick,

Since the link you provided shows a shower only with no tub, TheEplumber's question above is a good one.

Current standards limit the maximum water flow of shower heads to 2.5 gpm. 1/2 inch PEX tubing has a flow rate of 6 gpm but that's for the tubing only. If you use crimp or cinch fittings, the inside diameter of the fittings will be smaller so the flow rate will be less. But it will still be higher than 2.5 gpm and high enough even if you remove the flow constrictor from the shower head.

The Wirsbo/Uponor PEX system uses the expansion method for fittings so the ID of the fittings will be about the same as the 1/2 inch tubing. This should give you about 6 gpm.

Any PEX system using 1/2" tubing will give you more flow than one shower head needs.

$.02,
HRG
